I'm afraid I don't understand why anyone would, as a rule,
not send tax receipts to companies/corporate foundations for their matching gifts. Unless I misunderstood what you meant by receipt, John?
A matching gift payment may be a Very Very Special type of gift (and a leading cause of my Very Very Special headaches!

), but it's still a
gift. Any given MG potentially has an impact on the organization's taxes, the same as any other kind of corporate giving. Do you not send tax receipts to corporations/corporate foundations for their gifts that aren't a match for anything?
As a rule, we send tax receipts to MG companies for every MG payment they send us. Our receipts person does the vast majority of these right along with the rest of the daily receipting, so they take the same format as receipts for individuals or other corporate giving. (I'd bet that consolidated receipts--annual, quarterly, or whatever--would be fine in most cases, if that's how you preferred to do it.)
The only time we
don't send a receipt is when the MG company specifically asks for no receipt, which is not terribly common. If they don't say "no receipt, please," then I assume they want one. Sure, it's possible that they don't care, but better safe than sorry. If they don't need the receipt, they'll either let us know, or just chuck receipts as they come--that's their perogative, but I know my department has done right by the IRS.
. . . And, in fact, I've worked with a roughly equal (maybe a bit greater) number of companies who
do specify ask for a receipt/tax substantiation/acknowledgement that we received their check. A lot of those even ask me to use a specific medium to receipt them--e.g., do it through their website, or complete, sign, and return the enclosed form. In those cases, I'll take care of it myself, and mark the gift "Receipted" so it doesn't get in our receipts person's way.
Meanwhile, here's what we
don't send:
- Match companies do not get a tax receipt for the individual's gift (unless the match form specifically requests proof of the gift--they get a copy of the check, or of our receipt to the individual)
- The individual does not get a tax receipt (or hard credit!) for the match payment--it wasn't their money, therefore it wasn't their gift
- Nobody gets a tax receipt for the MG pledge, obviously, since it's not a gift--though the match expectancy may be mentioned on various communication with the individual
